ADJUSTMENTS
Ring and pinion gears are supplied as matched

pinion gear are etched into the face of each gear (Fig.
4). A plus (+) number, minus (±) number or zero (0) is
etched into the face of the pinion gear. This number
is the amount (in thousandths of an inch) the depth
varies from the standard depth setting of a pinion
etched with a (0). The standard setting from the cen-
ter line of the ring gear to the back face of the pinion
is 109.5 mm (4.312 in.). The standard depth provides
the best gear tooth contact pattern. Refer to Back-
lash and Contact Pattern in this section for addi-

Compensation for pinion depth variance is
achieved with a select shim/oil baffle. The shims are
placed between the rear pinion bearing and the pin-
ion gear head (Fig. 5).

Compensation for pinion depth variance is
achieved with a select shim/oil baffle. The shims are

ASSEMBLY
(1) Install differential side gears and thrust wash-
ers.
(2) Install differential pinion and thrust washers.
(3) Install the pinion shaft.
(4) Align the hole in the pinion shaft with the hole
in the differential case and install the pinion shaft
lock screw.
(5) Lubricate all differential components with
hypoid gear lubricant.
INSTALLATION
(1) Apply a coating of hypoid gear lubricant to the
differential bearings, bearing cups, and threaded
adjusters. A dab of grease can be used to keep the
adjusters in position. Carefully position the assem-
bled differential case in the housing.
(2) Observe the reference marks and install the
differential bearing caps at their original locations
(Fig. 29).
(3) Install bearing cap bolts and tighten the upper
bolts to 14 N´m (10 ft. lbs.). Tighten the lower bolts
finger-tight until the bolt head is seated.

adjustment procedure.
NOTE: Be sure that all bearing cap bolts are tight-
ened to their final torque of 136 N´m (100 ft.lbs.)
before proceeding.

for the quantity and type.
(9) Install the fill hole plug and lower the vehicle.
(10) Trac-lokydifferential equipped vehicles
should be road tested by making 10 to 12 slow figure-
eight turns. This maneuver will pump the lubricant
through the clutch discs to eliminate a possible chat-
ter noise complaint.
DIFFERENTIAL - TRAC-LOK
DIAGNOSIS AND TESTING - TRAC-LOKY
The most common problem is a chatter noise when
turning corners. Before removing a Trac-lokyunit
for repair, drain, flush and refill the axle with the
specified lubricant. A container of Mopar Trac-loky
Lubricant (friction modifier) should be added after
repair service or during a lubricant change.
After changing the lubricant, drive the vehicle and
make 10 to 12 slow, figure-eight turns. This maneu-
ver will pump lubricant through the clutches. This
will correct the condition in most instances. If the
chatter persists, clutch damage could have occurred.
DIFFERENTIAL TEST
The differential can be tested without removing the
differential case by measuring rotating torque. Make
sure brakes are not dragging during this measure-
ment.
(1) Place blocks in front and rear of both front
